IMPROVEMENT IN AUTOMATIC FASTENINGS FOR SASHES, &c.

Specification forming part of Letters Patent No. 143,982. dated October28, 1873; application lcd May 16, 1872.

To all whom it may concern:

Be it knownthat I, J osEPH HOLLELY, of the city of Brooklyn, eormty ofKings and State of New York, have invented certain Improvements inAutomatic Fastenings, of which the following is a specification:`

The object of my invention is to produce a simple and economical devicefor securing window-sashes, doors, drawers, and the covers of chests,&c., which device is so constructed and arranged that it forms afastening which acts and operates automatically to secure thewindow-sashes, door, or other object to which it may be applied withoutthe use of a key.

The above-mentioned object is accomplished mainly by the combining, withthe bolt which does the fastening, a tripping-lever and a spring, whichmay also aetuate the bolt. Then` this fastener is applied towindowsashes there is secured upon one sash a wedge-shaped piece ofmetal, which so receives a counterpart otl corresponding form attachedto the other sash, that, when the parts approach each other, the smallend ofthe wedger'ormed piece will be sure to `enter into the largeopening in the counterpart, and when the two parts to be securedtogether have arrived at nearly their final position, then theprojecting end ot1 the tripping-lever is thrown back, thereby freeingthe bolt, which, then, by the force of a spring, is thrown forward, andengages in a manner similar to an ordinary lock-bolt, thereby securingthe parts without special separate operation from any person whatever.

Figure l represents the working parts of an ordinary drawer-lock. Fig. 2represents, similarly, alock for a box or chest. Fig. 3 represents theworking parts of a window lock or catch. Fig. 5 represents a counterpartof the same fastening shown in Fig. 3. Fig. et represents part of theupper and part ot' the lower sashes of a window, provided with thefastening shown in Figs. 3 and 5.

Similar letters refer to corresponding parts in all the figures.

Fig. 4 shows the position of the parts after the wedge-shaped piece whas entered its corresponding recess W in the counterpart. The wedge andrecess for the same are more clearly shown in Figs. 3 and 5, at w and W.The tapering part of the wedge, shown in the plan view, Fig. 3, w,serves to guide 'and steady the counterpart, Fig. 5, in onedirection,while the doveta-iled form given to the same draws and holdsthe parts firmly together. B is the bolt which serves to secure theparts when they have arrived in proper position. T is thetripping-lever, hung upon the pin p, and working against a shoulder ornotch, n, in the bolt B, Vwhich works upon the pin p. S is the springwhich, secured to the stud d, serves to actuate the tripping-lever T andthe bolt B.

VThe tripping-lever T is provided with a striking end, c, which shouldbe beveled in cases where the parts to be secured move bysliding upon,or swinging near to,each other. The striking end c is made to Yprojectfrom the body of the fastening, so that it shall come in contact withsome part of,'or obstacle secured to, the object to be fastened, theobstacle being so placed asto hit the striking ende just as the parts tobe secured arrive at their proper position for tastening.

AIn Fig. 5, the point of the counterpart at o is t-hc obstacle whichacts upon the striking end c of the tripping-lever T, pressingthat endbackward and 4releasing the opposite end from the notch n in the bolt B,which then, being free, is thrown forward by the spring S and locks theparts together.

When it is desired to raise the lower sash from the inside it is onlynecessary to push the bolt B back by pushing upon the pin l), whereuponthe small end of the tripping-lever will iy into the notch n from theforce of the spring S, and retain the bolt in. the withdrawn positionduring such time as the parts are allowed to remain apart. 'W'hemhowever, the window is closed by intention or accident the automaticlocking is sure to take place.

In Figs. l and 2, an ordinary key will be required to withdraw the boltwhen the parts have been locked. o', in Fig. 2, is the opening in theedge of the lock through which the hasp or staple, secured to the coveror lid of the object, enters the lock to receive the bolt B.

I claim as my invention- The combination of the tripping-lever T andspring S with the` pivoted bolt or catch B, all arranged and operatingsubstantially as and for the purpose herein speciliet Dated May 2, 1872.

JOSEPH HOLLELY.
